Allen R Miller (1942–2010) was an American mathematician.
Miller was a major contributor to the field of special functions, especially confluent hypergeometric functions.
A native of Brooklyn, NY, Miller attended George W. Wingate High School and Brooklyn College, where he graduated in 1965 with a degree in Mathematics. Miller began his professional career at the Ballistics Research Laboratory at the Aberdeen Proving Ground where he worked with physicist Jane Dewey. In 1967 he moved to the Naval Research Laboratory where he developed high-fidelity mathematical models of interactions between physical systems and electromagnetic fields. Unlike most pure mathematicians of the time, Miller implemented simulations of his models on early supercomputers. In the 1970s Miller was recognized not only as a leading mathematician but also as an expert on the CRAY line of supercomputer.
Miller maintained an academic affiliation with George Washington University as an adjunct professor after retiring from the Naval Research Laboratory in 1991. He published actively until his death from a heart embolism on August 15, 2010.
